Compact Unit Heater ® Class I, Divisions 1 and 2, Group D Class I, Zones 1 and 2, Group IIA American Bureau of Shipping INDEECO’s COMPACT explosion-proof unit heater is designed with both size and economy in mind. COMPACT advantages and unique features include: • Compact Size: This small design is only 13 inches wide, which makes it ideal for applications where limited space is available. • Low Cost: The COMPACT design offers the most economical solution for heating small Class I, Group D hazardous areas. It is a cost effective alternative to the use of explosion-proof convection heaters. Applications •Chemical Storage/Handling Areas •Oil Platforms and Refineries •Compressor Stations •Sewage/Wastewater Treatment Plants • Marine and Offshore •Spray Booths • Redundant Overtemperature Protection: Primary and secondary automatic reset thermal cutouts for additional safety. • Stainless Steel Construction: Provides superior corrosion resistant protection. Optional Dirty Duty construction adds polyester powder coating to all aluminum parts for use in corrosive applications. • Optional Marine Duty Construction: The COMPACT design is ideal for shipboard use where size, weight and corrosion resistant construction are critical. Standard Construction Features Heating Elements – Industrial grade, Type 304 stainless steel finned tubular heating elements are manufactured by INDEECO. Terminal Enclosure – A NEMA 7, 9 cast aluminum enclosure with a threaded bottom cover permits easy access to the built-in controls from underneath the heater. Housing – Round, 16-gauge stainless steel shroud. Grilles – An adjustable stainless steel louvered outlet grille directs airflow 45° up or down and a heavy gauge stainless steel rear grille protects against accidental contact with the fan blade. Built-In Controls – Include primary and secondary automatic reset overtemperature cutouts, controlling contactor, and a time delay relay which keeps the fan running to cool the heating elements after they have been de-energized. Fan Motor Assembly – Consists of a 120-volt, 1-phase 60 hertz motor fitted with an aluminum fan blade. The totally enclosed motor is UL Listed for Class I, Group D applications and includes permanently lubricated ball bearings and built-in thermal overload protection. The motor is factory wired into the enclosure to reduce field wiring, but requires a separate 120-volt power supply. Stainless Steel Swivel Mounting Bracket – Supplied as standard with all COMPACT explosion-proof unit heaters. This multi-purpose bracket can be used for either wall or ceiling mounting. 14 www.indeeco.com 800-243-8162 Compact Unit Heater Custom Options Code Option M Dirty Duty Corrosion Resistant Construction Marine Duty Construction Manual Reset Cutout T Adjustable Thermostat C CM Availability Code (2) Description Includes polyester powder coated fan blade, wiring conduit and fittings, NEMA 4X, 7, 9 enclosure.
